Misadventures of a family of sex maniacs. Mum demands her husband screw her instead of, as she correctly suspects, everything else in a skirt. Daughter is a police inspector who frisks suspects, including their family jewels and, if they're sufficiently well-endowed, takes them in for "questioning". Younger son seduces a photo model who is the mistress of a gangster as well as his (widowed) sister-in-law, who herself demands sex at least six times a night.
